For producers looking to source DOA (dioctyl adipate), the right quote starts with the right information. The product’s identity, the application, quality expectations and logistics needs directly affect what the quote contains. In this article we have compiled, as a checklist, the information worth sharing when requesting a DOA quote and points to consider.
1. Product identity
Identifying DOA by its common name, chemical name and CAS number prevents confusion: dioctyl adipate, bis(2-ethylhexyl) adipate (DEHA), CAS 103-23-1. For more, see our article DOA (Dioctyl Adipate) Chemical Identity.
2. Application
State which product you will use DOA for: cable, seal, artificial leather, plastisol or another application. The application determines which quality parameters matter most. If your product has a particular environment of use (for example cold or outdoor) or specific requirements, include those too.
3. On its own or in a blend?
It helps to state whether you will use DOA on its own or with another plasticizer such as DOTP. If you use a blend, you can add your DOTP need to the same request. For the blend logic, see our article DOA and DOTP Blends.
4. Quality criteria
Share the technical parameters critical to your process. Parameters such as colour, ester content, acid value, water content and viscosity appear in the technical data sheet. If you work to an existing specification, sharing it helps the quote match your expectations. Values are confirmed per product and batch.
5. Packaging
State the packaging type that suits your site’s storage and unloading facilities. Packaging options are clarified at the quote stage.
6. Quantity and frequency
State your approximate quantity and whether the need is one-off or regular. For regular consumption, sharing your approximate monthly or periodic need makes planning easier.
7. Shipping
The delivery address, your site’s unloading conditions and your preferred shipping method are important for the quote. If you are requesting from abroad, state the country and shipping method too.
8. Documents
If you need documents such as a TDS, SDS or analysis report, mention it in your request. Which documents are shared at which stage depends on the product and the request. For the difference between a TDS and an SDS, our article DOTP TDS and SDS also offers a general framework for DOA.

Our raw materials range
Along with DOA, we also quote for DOTP plasticizer and PVC plastisol. You can browse our whole range on the raw materials page.
Requesting technical documents
Stating the technical documents you need at the outset speeds up the quote process. Documents such as the technical data sheet and safety data sheet are needed for your quality and occupational health teams’ assessment. You can also state which language you need the documents in.
Long-term cooperation
For sites using DOA regularly, sharing consumption forecasts periodically makes supply planning easier. If your production programme has seasonal swings, for example increases ahead of winter for cold-environment products, letting us know in advance helps plan orders on schedule. Information such as packaging preference, delivery address and storage conditions also helps finalise the quote.
If you use DOA together with DOTP, you can send your request for both products in a single form.
Frequently asked questions
Can I request a quote without knowing the exact quantity?
Yes. An approximate quantity is enough for an initial assessment.
Can I request DOA and DOTP in the same quote?
Yes. You can state your need for both products in the same request.
